West Palm Beach police said the 26-year-old victim's father found his son dead inside the living room of the apartment.

Detective Greg Key said the father found Gerard Gonsalves Jr. "in a pool of blood" and called police.

Investigators haven't said how he died.

Police have named his brother, Brandin Gonsalves, as a person of interest.

"Its our belief that he has some information in regards to the case or he could be a victim himself because we can't find him anywhere, and normally he's at the house when the other brother's there as well," Key said.
